Method for keeping architecture, software and hardware conforming in configurable chip operating system

Abstract

The invention provides a method for keeping architecture, software and hardware conforming in a configurable chip operating system. The method includes steps of describing an architecture model of a CSOC (configurable system on chip) system by hardware description language; describing a software model on the basis of the architecture model through configuration parameters and behavioral level description by hardware description language; and describing a hardware model on the basis of the architecture model by the hardware description language. By the method for keeping architecture, software and hardware conforming in the configurable chip operating system, design process of the CSOC system can be greatly simplified, and a great quantity of repeated work can be reduced.

Description

technical field [0001] The invention relates to the field of microelectronics, in particular to a CSOC chip design method. technical background [0002] CSOC (Configurable System On Chip) configurable system on chip is a system that integrates FPGA (Field Programmable Gate Array) and embedded processors (ARM, 8051, MIPS, etc.) on one chip, and integrates FPGA configurable features and processing The flexibility of the device has been more and more widely used. Due to the introduction of FPGA in CSOC system, special software support is required. In the traditional CSOC system design method, software and hardware design are basically two independent branches. It is difficult to guarantee the co-design of software and hardware. The consistency of software and hardware design can only be guaranteed through a large number of simulations and verifications in the later stage, which is time-consuming and inefficient. high.

Problems solved by technology

In the traditional CSOC system design method, software and hardware design are basically two independent branches. It is difficult to guarantee the co-design of software and hardware. The consistency of software and hardware design can only be guaranteed through a large number of simulations and verifications in the later stage, which is time-consuming and inefficient. high

[0003] A big difference between CSOC and ASIC and ASSP design is that in addition to completing hardware design, CSOC also needs powerful software support, which puts forward high requirements for the collaborative design of software and hardware. In addition, because it involves software and hardware Two aspects, so it is difficult to effectively evaluate the system design in the early stage
